SPECIFICATION forming part of Letters Patent No. 660,992, dated October30, 1900.

Application led December 22, 1898. Serial No. 700,084. (No model.)

To .all whom t may concern:

Be it known that I, JOHN S. KIDD, a citizen of the United States ofAmerica, and a resident of Des Moines, in the county of Polk and Stateof Iowa, have invented a new and useful Wagon-Dump and Elevator, ofwhich theV My invention consists in the construction,Y

arrangement, and combination of elements hereinafter set forth, vpointedout in my claims, and illustrated by the accompanying drawings, inwhichy Figure 1 is an elevation in section of a form of my machine inwhich a receptacle is formed in the platform and which employs a lateralconveyer to remove the grain from the receptacle to an elevator-leg.Fig. 2 is a plan of the machine shown in Fig. 1. Fig. 3 is a detailedside elevation, partly in section, of the lateral conveyer. Fig. 4 is adetailed elevation of a portion of the mechanism employed to oscillatethe wagonplatform and elevate the grain. In the construction of theapparatus as shown the numeral 101 designates a platform fulcrumed at99, its rear end in a supportingframe 102 and resting at its forward endin a supporting-frame 103, connected to the frame 102. Aplatform-approach 104 is fixed at its forward and upper end tothe frame102, coincident with the rear end of the platform 101. An opening isformed in the approachplatform 104, and a hopper 105 is located beneathsaid opening, which hopper has a forwardly-discharging port 106,extending its entire length and communicating with a oo nveyer-trough107. Atrap-door 108 is hinged to the forward end of the upper edge ofthe hopper 105 and when said hopper is closed rests upon cleats 109,fixed to the interior faces of the ends of the hopper. A trap-door 110is hinged to the upper edge of the rear portion of the hopper 105 andwhen said hopper p is closed rests on the trap-door 108, thereby forminga portion of the passage-way or approach to the main platform. The endsof the hopper 105 are extended upwardly, forwardly, and rearwardly fromthe approach 104 to form wings 111 and are provided with cleats 112 ininclined positions,on which cleats the doors 108 110 rest when thehopperis open. A drum-shaft 113,is horizontally positioned transverselyof the left end of the con veyertrough 107, and a drum-shaft (not shown)is mounted 'at the opposite end of said conveyer-l trough. A conveyer114 is mounted on The drum-shafts and comprises a belt having lat.

A clutch member 122 is formed on asprocketwheel 121, and a clutch member123, mounted for longitudinal movementon the shaft 20,

meshes at times with said clutch mem-ber 122. A lever 124 is provided,whereby the clutch member 125 may be moved longitudinally of the shaft20. y An elevator Wheel or drum 125, provided with a short hub 126, ismounted on the stub-axle 118, the said hub extending less than half thelength of the face of the wheel. The rim of the wheel125 is formed of aseries of bars in a row concentric with the axle 118 and paralleltherewith, and the outer ends of said bars are connected by a ring 127,which ring surrounds the aperture 116 in the ele vator-leg, thus forminga drum-wheel of skeleton shape which may be fed to its interior from theconveyer trough 107. Sprocket. teeth 128 are formed on the arms of thewheel 125 and may carry a sprocket-chain (not shown) to whichelevator-buckets 129 are attached. -It will be observed that spacesbetween the bars of the wheel 125 and between the elevator-buckets 129provide means for depositing the grain from the conveyertrough into thebottom of the elevator-leg IOO , coincident with the elevation of thegrain by the buckets 129.

The forward end of the platform 101 is connevted by a cable 136,extending over a sheave (not shown) on the upper end of the frame anddownwardly to the shaft 20, as follows: A wheel formed of a pair ofdisks 137, arranged in close relation to each other and connected, ismounted on the shaft 20 loosely, and the lower end of the cable 136 isconnected to said wheel. A friction-clutch 138 is keyed to the shaft 20and engages at times with the wheel 137. A ratchet 139 is formed on thewheel 20 and is engaged at times by a pawl 1-'10 to prevent reversemovement of said wheel. A horse-power, as described in my application,Serial No. 594619, filed June 6, 1896, may be applied to the shaft 20,and when so applied the operation of the machineis as follows: Thetrap-doors are closed. A loaded wagon is drawn upon the recu mb'entplatform 101 and chucked against rearward and forward movement thereonby means of the chuck described in my application above The trap doorsare opened against the cleats 112. The clutch 123 is engaged with theclutch 122. The clutch 138 is engaged with the wheel 137. The horsepoweris operated so that the shaft 20 is rotated, and the cable 136 is woundon the wheel 137 and elevates the front end of the platform 101 and thewagon thereon into the desired posilion, with the rear end of thewagon-box projecting over the door 108 toward the center of the hopper.The clutch 13S is released from the wheel 137 and said wheel is retainedbythe pawl 140 and ratchet 139 in engagement. The tail-gate of thewagon-box is opened. The grain runs from the wagon-box into the hopperand from the hopper into the con veyer-trough. rlhe chain 120 rotateslthe sprocket-wheel 119, axle 118, hub 126, and wheel 125, and therebyoperates the elevator-buckets to receive the grain from theconveyer-trough and elevate the same as desired. Simultaneously with theoperation of the elevator the sprocket-wheel 130, chain 131,sprocket-wheel 132, shaft 133, bevel-gear 134, bevel-gear 135, and shaft113 are operated to drive the conveyer 114.- in such a direction thatthe flights 115 on the lower portion of said conveyer move and carry thegrain along the trough and deliver the same through the aperture 116into the interior of the wheel 125, and thence to the bottom of theelevator-leg to be received and elevated by the buckets 129. When thementioned.

grain is all elevated, the horse-power is stopped, and the platform 101is let do'wn by releasing the p'awl 140 from the ratchet 139 andcontrolling the reverse rot-ation of the wheel 137 by thefriction-clutch 138. The trap-doors 108 110 are then closed upon thecleats 109, the wagon'withdrawn over the horse-power to the ground, andthe machine 'is in a position to receive and elevate another load ofgrain.

The machine may be mounted on trucks and transported as desired.

One of the advantages I claim for this form of machine is that the wagonrests entirely on the hinged platform 101, and in elevating saidplatform the distance required to locate the wagon-hox at a proper anglerelative to the horizontal to deliver the grain over the top of the door108 I am enabled to lift the rear of the wagon several inches fartherthan if the wagon were tilted on the axis of the rear axle, resulting ina gain of several inches in the height of delivery, or a correspondinggain of several inches in a distance required to haul the wagon upon theplatform 101 in the first instance.

By employing the ends 111 of the hopper, extended above the platform andforwardly and rearwardly from the portion of the hopper below theplatform, and providing the cover of the hopper in two sections soarranged as to be positioned at right angles to form extensions to thefront and rear sides of the hopper, I am enabled to provide a receptaclewhich will contain the amount of grain that may be hauled upon theplatform in the wagon-box.

If desired, such connections may be made between the platform 101, thepower-shaft 20, and the elevator as will lift and tilt the wagongradually and operate the conveyer and elevator rapidly, so that whenthe wagon is tilted sufficiently to discharge the last por-` tion of itsload into the hopper nearly if not quite all the contents of the hopperwill have been removed and elevated. It' such connections are made, thehopper may be of less capacity, sufficient only to receive a portion ofthe load gradually until all of the load has passed through said hopper.With such an arrangement the platform 101 could be fulcrumed materiallycloser to the ground, and by so doing the hauling of the wagon severalinches in elevation might be avoided.

I claim as my invention- 1. In a wagolrdump and elevator, aWagonplatform arranged foroscil1ation,an approach platform, a Well orhopper in said approachplatform, trap-doors arranged to close the top ofsaid well or hopper at times and be elevated and form extensions of saidhopper at times, side pieces 111 arranged above the platforms andforming extensions of the ends of the hopper and means for removinggrain from said hopper.
